A. Field of Invention
This invention pertains to musical instruments with removable mouthpiece assemblies, and more particularly to a novel assembly wherein the ligature has several positions spaced along a longitudinal axis of a mouthpiece.
B. Description of the Prior Art
Woodwind instruments are instruments consisting of a tubular body used to define a column of air. As is well known in the art, sound waves are produced within the column of air and the musical characteristics of the sounds, including pitch, volume and other characteristics are modulated by changing the acoustic characteristics of the column. More specifically, a mouthpiece is attached by a friction fit to an end of the tubular body. The mouthpiece has a cavity in communication with the interior of the tubular body. A reed covers the cavity and is arranged so that when a musician blows through the mouthpiece, the reed oscillates and produces vibrations which are then propagated through the cavity in the mouthpiece to the tubular body. The reed is secured to the mouthpiece by an adjustable metal band known as the ligature.
The ligature normally extends circumferentially around the entire outer body of the mouthpiece. The ligature is provided with an integral tightening mechanism that is used to secure the reed to the mouthpiece. Because of the mechanical coupling between the ligature, the mouthpiece and the reed, the structure of the ligature plays a roll in the sound produced by the instruments, and various types of ligatures are available from different companies, each having its own sound characteristics.
A mouthpiece assembly includes a tubular mouthpiece a sidewall formed with a longitudinal portion and a ligature for securing a reed to the mouthpiece. The mouthpiece and the ligature are sized and shaped to define a plurality of discrete positions for the ligature. The ligature can secure the reed at each of its positions in a manner that allows the reed and the ligature to vibrate during play. In one embodiment, the mouthpiece has a longitudinal portion formed with spaced holes. The ligature includes a movable shaft that can be selectively inserted and retrieved from the holes to adjust the position of the ligature or remove it. Preferably, the holes are oversized so that the shaft fits loosely into the holes. The ligature has a threaded transversal hole and the shaft is threaded and is positioned in the transversal hole so that it can be selectively advanced into, or retracted from the holes in the mouthpiece.
In order to provide a better understanding of the invention, some prior art ligatures are first discussed. Referring first to
It is well known that the position of the ligature on the mouthpiece has an effect on the sound produced by the respective instrument and therefore, once a musician locates the ligature position on a particular instrument, he would like to be able to mount the ligature in exactly the same position. A problem with the prior art ligatures, such as the two shown in
Also, in the attempt to hold the ligature in place previous art ligatures utilize large surface areas of tight contact with the mouthpiece body 102. Not only does this only moderately work, but most importantly the vibrations of the reed/ligature combination are dampened by the mouthpiece body 102 creating a severely deadening affect on the resultant sound produced by the mouthpiece.
Referring to
The ligature 100 is used to mount a reed 104 on a mouthpiece 102B. Mouthpiece 102B has two elongated sections 107 on its sides, each section 107 being formed with holes 110 spaced longitudinally. The holes are sized so that the screws 109 can loosely fit into holes 110. Once positioned, the screws 109, held securely in the ligature by threaded holes 108 in the ligature, hold the ligature securely in place along mouthpiece 102B by immovably fitting in holes 110. This allows the ligature to vibrate freely in relation to the mouthpiece, while still securely being held in place.
As shown in
Most importantly because the set-screws 109 are loose inside the holes 108 only minimal contact, and NO frictional contact, is had with the mouthpiece body 102B. This allows the reed 104 and ligature body 106 combination to vibrate independently from the mouthpiece body 102B and a free, open, and resonant resultant sound to be produced.
Of course other means can be used to engage the ligature to the mouthpiece. For example, the set screw can be replaced by a spring-loaded shaft that can be easily inserted into and withdrawn from holes 110. Further, the set screws could be loose inside the ligature holes 108 and screw into threaded holes 110. Numerous modifications can be made to the invention without departing from the scope defined in the appended claims.
